The process of loading bulk materials onto automobiles at storage sites is bulk material loading. Bulk materials are shipped to and from the vehicle by a series of equipment and mechanisms such as loading bins, motorized arc doors, etc. In the traditional loading mode, a vehicle drives on a loading platform, the front end of a carriage is required to be aligned to a feed opening of a storage bin under the command of field personnel, and after the carriage is aligned to be stopped, an electric arc door is opened to start discharging. When bulk materials are accumulated in the carriage and the height is close to that of the guardrail plate, the electric arc door is closed, on-site personnel command the vehicle to move forward for a proper distance, and the electric arc door is opened to continue discharging.
